Answer:
A. A volcano erupts on a small island.
C. Flooding loosens dirt and rocks along a hillside.
Explanation:
Tectonic activities and mass wasting will greatly lead to a change in land forms on earth's surface.
When a volcano erupts on a small island, a change in landform often results. Also, flooding can lead to changes in land form.
- Volcanic eruptions generally adds new materials to the earth surface.
- Magma that reaches the surface called lava deposits rock materials unto the surface.
- During an extensive period of flooding, materials are carried from one place to another and this greatly sculpts the surface of the earth.

Answer:
0.82052 m
Explanation:
potential energy of spring = kinetic energy
=> 0.5kx^2 = 0.5mv^2
=> 
v= 3.11127 m/s
angle = 37°
thus height = distance×sin(37) = D×0.60182
Also,
m×g×h = 0.5×m×v^2
=> 2×9.8×D×0.60182 = 0.5×2×3.11127×3.11127
=> D = 0.82052 m
